Abstract

Electrode destinée à être utilisée pour effectuer une réaction électrolytique. L'électrode comporte un support ou substrat en métal de valve qui porte sur au moins une partie de sa surface exposée un mince revêtement d'enrobage électroniquement conducteur et électrocatalytique ayant une épaisseur utile pour effectuer une électrolyse entretenue, ce revetement, à l'exclusion de tout diluant ou additif, étant essentiellement amorphe et ne présentant aucune cristallinité détectable par analyse de la diffraction des rayons X. Application aux électrodes utilisées, notamment, pour la fabrication de chlore et d'hydrochlorite, pour la production de composé organiques ou pour l'électrolyse de l'eau.Electrode intended to be used to carry out an electrolytic reaction. The electrode has a valve metal support or substrate which bears on at least a portion of its exposed surface a thin electronically conductive and electrocatalytic coating coating having a thickness useful for effecting sustained electrolysis, this coating excluding of any diluent or additive, being essentially amorphous and exhibiting no crystallinity detectable by X-ray diffraction analysis. Application to electrodes used, in particular, for the manufacture of chlorine and hydrochlorite, for the production of organic compounds or for the electrolysis of water.
